I have T1 HWIC in slot 2 and T1 Network module in slot 2 . Router is 3845.
If I configure first HWIC T1 for channel-group 0 timeslots 1-24 speed 64 then I'm not able to configure Module T1. I'm getting this error:
Router(config-controller)#channel-group 0 timeslots 1-24 speed 64
%Insufficient resources to create channel group
*Jul 30 21:52:23.111: No Free HDLC resources (8)
If I configure first Module then I'm not able to configure HWIC. Do you know why ? Are they sharing some resources ?
NM-HDV module supports a maximum of 32 HDLC channels with a bandwidth of 2
Mbps. So, when you configure timeslots, since you have already configured 24
slots on one card, you can at the maximum support 8 on the second.
Data Features (Only Supported on NM-HD-2VE)
. Support serial data WAN access using T1/E1 or fractional T1/E1 network
. N X 64 Kbps or N X 56 Kbps channel group data rates (T1:N=1 to 24, E1:N=1
. Supports up to 32 data channel groups with a total bandwidth of up to 2

Hope this answers your questions.
